The Sound Technician

We often see these guys during a concert. They are the ones who go up on stage before a performance and conduct mic checks. We see them hauling large cables and adjusting the levers or knobs of a mxing console. They are sound technicians, the people who makes sure every sound or audio can be heard as clearly and well-balanced as possible during a performance.
